Southern Ag - Liquid Copper Fungicide - Fungicide, 16oz

This stuff works excellent on my plants and grass

Did the trick! Kept the fungus and mildew away on my roses.

It sprays very well.

This is a good quality product, easy to use. I added a teaspoon to a 32oz spray bottle of water to use on my peonies to prevent botrytis.

This is the most reliable brand I have used on my mango tree. For spot free fruit this is the best for me in southwest Florida. I use this in an Ortho hose end sprayer for a 30-foot tree. Shipping is fast and reliable.

We don't think this works.

> Great for controlling fungus on fruit trees and vegetables, because copper sulfate in small quantities is not toxic to human beings. If your fruit or vegetables absorb a little copper, they are perfectly safe to eat.> It actually needs to touch the surface of the plant that is affected---that is, both the top and bottom sides of leaves, and needs to set there for a while. So, spray from multiple angles, and don't apply unless you expect conditions to be dry for say 6 hours or more.> Can kill or repel snails and slugs, since they are very sensitive to copper.> I mostly spray it on my citrus and mango trees. For some varieties of mangos it is essential in order for the flowers to set (i.e., develop into fruit). I also paint undiluted copper sulfate on tree wounds (e.g., such as those caused by trimming a limb).> It is recommended not to use it on orchids or bromeliads---but I've had no choice when I've treated trees which had orchids and bromeliads growing on them--but the orchids and bromeliads seem to tolerate it with no problem.> Copper sulfate mostly works on the surface of the leaves, kills the surficial fungus, and is washed off with the next rain -- very little is absorbed. Copper sulfate is ineffective against (systemic) fungal infections of the stems or roots, since it is NOT absorbed at significant levels. That means little gets into the fruit or vegetables.> If you have serious fungus problems on non-fruit trees or other ornamentals (such as roses), you may need a systemic fungicide. I use Monterey Agri-Fos Systemic Fungicide 32oz.IS COPPER TOXIC?> Sure, copper is toxic in excessive concentrations. So is virtually every natural chemical element. Salt is sodium chloride (sodium and chlorine), right? --- both of which are VERY toxic. But both sodium and chlorine (both together and separately) are absolutely essential to human health. Copper is also ESSENTIAL to human nutrition --- you can even buy copper supplements on Amzn . The question is the concentration. At the recommended concentrations, copper sulfate is safe to apply and use. At the recommended concentrations, the amount of copper absorbed into fruit and vegetables is negligible. The water pipes in your home are probably copper -- you'll get far higher doses of copper from your drinking water, than you'll ever get from eating tomatoes -- and that copper may be beneficial to your health.> Obviously, it is best to minimize breathing copper sulfate mist for long periods of time, or soaking your bare skin with copper sulfate solution for long periods. It is best to take care disposing of excess copper sulfate solution --- although simple dilution (with more water), or spreading the excess over an area, is probably adequate care. Don't pour directly into a stream. But copper sulfate isn't like an insecticide or systemic fungicide where you need to wear a respirator and rubber gloves to use safely. For household garden use, no special precautions are necessary.

Very good product. Cured fungal disease on my tomato plant & my Hydrangea bush.
